We divide 21961903 by 9
We're looking to find how many times 9 goes into 21961903.

Going ahead to step 1:
2 divided by 9 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 9

Let's proceed to step 2:
9 can be fit into 21 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 18 from 21 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 9

Moving on to step 3:
When dividing 39 by 9, we get 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we subtract 36 from 39, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 9

Advancing to step 4:
If we divide 36 by 9, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 244.0
If we subtract 36 from 36, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 9

Going ahead to step 5:
9 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 2440.0
Subtract 0 from 1 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 9

Let's proceed to step 6:
The number 9 fits into 19 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 24402.0
The remainder is 1 after subtracting 18 from 19.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 9

Step 7:
The number 9 fits into 10 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 244021.0
Deduct 9 from 10 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 9

Let's proceed to step 8:
If we divide 13 by 9, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 2440211.0
Subtract 9 from 13 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
9 can be fit into 40 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 2440211.4
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
9 can be fit into 40 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 2440211.44
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 2440211.44 with a balance of 0.004.
